What type of motors are classified under Class H?

Class H motors are classified as high temperature motors. This classification indicates that these motors can operate at higher insulation temperature ratings, allowing them to function effectively in environments with elevated temperatures. Motors designated under Class H typically have insulation materials rated for continuous operation at temperatures up to 180 degrees Celsius (356 degrees Fahrenheit).

This high temperature capability is crucial in applications where heat generation is prevalent, allowing the motors to maintain performance without the risk of insulation failure due to overheating. In contrast, classifications related to low, medium, or high torque motors primarily focus on voltage levels or mechanical output, which do not directly relate to the thermal endurance characteristics that define Class H motors.
